1PC LCD Display Digital Pupilometer Optical PD Interpupillary Distance Meter

Features: It is an ideal digital precision optical meter for measuring distance between human pupils in the process of optometry. With the scientifical design and technologies in optics and microelectronics, this device has the most exactitude configuration, and is able to measure more correctly. It also has the adjustable focusing knob to adjust the distance. Moreover, the lens is coated. The pupil distance is measured by making the pupillary light point and measuring light in direct line,in monocular or binocular way. Effective Range of Measurement: Binocular pupillary distance: 45 - 82 mm Left or right papillary distance: 22.5 - 41 mm Indication Error: ≤ 0.5 mm Rounding Error: ≤ 0.5 mm Distance of Target: 30 cm - infinity Power Supply: DC 6 V; 2 x 7# AAA Battery (Battery is not included.) Time for Automatic Shut-off: About one minute after stopping operation Dimensions: 210 x 137 x 50 mm Weight: 0.8 kg Package included: 1 x Digital pupilometer
